Question

the perimeter of a rectangle is a rational number. the length of a rectangle is 6 units. the width of a rectangle must be a/an rational/irrational (circle one) number.

Answer 1

Answer:

A rational number

Explanations:

The perimeter of a rectangle is given by the formula:

Perimeter = 2(Length + Width)

The Length = 6 units

Perimeter = 2 (6 + Width)

Perimeter = 12 - 2 Width

2 Width = 12 - Perimeter

Width = (12 - Perimeter)/2

Note that a rational number is a number that can be written as a fraction of two integers.

Since the perimeter is said to be a rational number, any rational number substituted into the formula equation for the width above will give a rational number.

The width of the rectangle is therefore a rational number
